智能运动手环设计 摘要当今社会随着人类的生活水平提高，大家对各自的健康问题有了更大的关心，只有一个好的身体才能体会生活，但是怎么才能让大众更好的去了解自己的身心健康呢？电子信息技术和医学刚好都在同步发展，两者合二为一刚好可以解决人们对于健康问题的困扰，因此人们对于高精密便携式医疗监控仪器的需求更大了。人体监控指标普遍通过心率计步两大指标，由于这个原因，本次毕设根据时代发展的需求设计一款基于单片机的运动监测模块。本次设计主要组成是 MSP430F149 单片机电路、ADXL345 加速度传感器、心率检测模块电路、LCD1602 液晶显示电路、电源电路组成。通过 ADXL345 测量重力加速度，是用来判断人体状态，根据状态的数值变化进行计步功能。通过心率传感器测试，通过手指脉动放大经过比较器处理后发送给单片机进行心率采集。并将步数、心率显示在液晶 LCD1602上。本次设计系统价格成本较低，功能比较全面，具有良好的市场前景。关键字：单片机；心率；步数；智能手环Design of Intelligent Sports Hand Ring AbstractNowadays, with the improvement of people's living standards, people have greater concern for their health problems. Only a good body can experience life. Therefore, health problems are getting more and more attention from the public. But how can we let the public better understand their physical and mental health? Electronic information technology and medicine are developing at the same time. The combination of the two can solve people's health problems. Therefore, people need more high-precision portable medical monitoring instruments. Human monitoring indicators generally pass through two major indicators of heart rate meter step. For this reason, a motion monitoring module based on single-chip computer is designed according to the needs of the development of the times.This design mainly consists of MSP430F149 MCU circuit, ADXL345 acceleration sensor, heart rate detection module circuit, LCD1602 LCD display circuit, power supply circuit. The measurement ...
